Description

냉장고의 냉장실 냉기조절구조Refrigeration room cold air control structure

본 고안은 냉장고의 냉장실 냉기조절구조에 관한 것으로 보다 상세하게는, 송풍팬에서 토출되는 냉기중 냉장실로 공급되는 냉기량을 조절하도록 설치되는 냉장고의 냉장실 냉기조절 구조에 관한 것이다.The present invention relates to a refrigerator compartment cold air control structure of the refrigerator, and more particularly, to a refrigerator compartment cold air control structure of the refrigerator installed to adjust the amount of cold air supplied to the refrigerator compartment during the cold air discharged from the blowing fan.

일반적으로 하나의 송풍팬에 의해 냉동실 및 냉장실에 냉기를 공급하는 냉장고는 도 1 및 도 2에 도시된 바와 같이 송풍팬(50)에 의해 흡입되어 토출된 냉기중 일부는 전방의 냉동실(30)로 공급되고 나머지 일부는 냉동실(30) 루버 A(23)와 루버 B(25) 사이에 형성된 냉장실 냉기덕트(15)를 통해 냉장실(20) 배면 중앙 상측으로 유도되어 덕트커버(2)에 형성된 냉기토출구(9)를 통해 냉장실(20) 내부로 공급되게 된다.In general, a refrigerator that supplies cold air to the freezer compartment and the refrigerating compartment by one blower fan is partially sucked and discharged by the blower fan 50 as illustrated in FIGS. 1 and 2 to the front freezer compartment 30. The remaining part is guided to the upper center of the rear surface of the refrigerating compartment 20 through the refrigerating compartment cold air duct 15 formed between the freezer compartment 30 louver A (23) and the louver B (25), and the cold air outlet formed in the duct cover (2). Through the (9) is to be supplied into the refrigerating chamber (20).

이때 냉동실(30)과 냉장실(20)에 각각 공급되는 전체냉기량의 비율은 냉동실 8:냉장실 2의 비율로 공급되게 된다.At this time, the ratio of the total amount of cold air supplied to each of the freezing chamber 30 and the refrigerating chamber 20 is supplied at a ratio of the freezing chamber 8: the freezing chamber 2.

그런데, 이와 같은 종래 냉장고는 루버 A(23)와 루버 B(25)에 의해 형성된 냉장실 냉기덕트(15)상에 상기 냉기덕트(15)의 통로를 개폐하는 조절판(10)을 좌우이동가능하게 설치하고 그 조절레버(12)를 냉동실(30)배면의 루버 A를 관통하여 냉동실(30) 내부로 노출되게 설치하여 식품량 및 온도 즉 열부하에 따라 냉도실(30) 및 냉장실(20)의 냉기량을 조절하도록 되어있다.By the way, such a conventional refrigerator is installed on the refrigerating chamber cold air duct 15 formed by the louver A (23) and louver B (25) so as to move the control plate 10 for opening and closing the passage of the cold air duct (15). The control lever 12 is installed through the louver A on the rear surface of the freezing chamber 30 so as to be exposed to the inside of the freezing chamber 30, and according to the amount of food and temperature, that is, the heat load, the cold air of the cold chamber 30 and the refrigerating chamber 20. To adjust the volume.

그러나 이와 같은 종래 냉장고의 냉장실 냉기조절구조는 조절레버(12)가 냉동실(30)배면의 루버 A(23)에 설치되어 있어서 그 앞에 냉동식품이 수납되어 있을 경우 조작이 매우 불편하고 냉장실 냉기덕트(15)의 개폐량을 조절하는 조절판(10)이 송풍팬(50)에 인접하여 있으므로 상기 냉기덕트(15)를 통과하는 냉기의 압력이 커서 조절판(10)을 냉기 통로의 개폐량을 조절하여도 실제로는 거의 동일한 량의 냉기가 냉장실로 공급됨으로써 미세조정이 어렵다는 문제점이 초래되었다.However, in the refrigerator compartment cold air control structure of the conventional refrigerator, the control lever 12 is installed in the louver A (23) on the rear side of the freezer compartment 30, so when frozen food is stored in front of the refrigerator, the refrigerator compartment cold air duct ( Since the control plate 10 for adjusting the opening and closing amount of 15) is adjacent to the blower fan 50, the pressure of the cold air passing through the cold air duct 15 is large, so that the control plate 10 may adjust the opening and closing amount of the cold air passage. In fact, almost the same amount of cold air is supplied to the refrigerating chamber, which causes a problem of difficulty in fine tuning.

본 고안은 이와 같은 종래 문제점을 감안하여 안출된 것으로서 냉장실로 공급되는 냉기를 쉽게 조절할 수 있으며 미세한 조절이 가능한 냉장고의 냉장실 냉기조절구조의 제공을 그 기술적 과제로 한 것이다.The present invention has been made in view of the above-mentioned conventional problems, and the technical problem is to provide a refrigerator compartment cold air control structure of the refrigerator which can easily adjust the cold air supplied to the refrigerator compartment and finely control.

도 3은 본 고안에 따른 냉장실 냉기조절구조를 나타내는 냉장고의 요부측단면도이고, 도 4는 일부절개 요부사시도로서 냉동실 루버 A(23)와 루버 B(25) 사이에 형성된 냉장실 냉기덕트(15)의 하단의 냉장실(20) 배면중앙의 상측에 덕트커버(1)가 설치되는데 상기 덕트커버(1) 내의 냉기통로(2) 배면에 좌우로 이동가능하게 개폐판(3)이 설치되어 개폐판(3) 이동에 따라 상기 냉기통로(2)의 개폐량이 조절된다.3 is a sectional side view of a main part of a refrigerator showing a refrigerating compartment cold air control structure according to the present invention, and FIG. 4 is a partial cutaway recessed perspective view of the refrigerating compartment cold air duct 15 formed between the freezer compartment louver A (23) and the louver B (25). A duct cover 1 is installed above the rear center of the rear side of the refrigerating compartment 20, and an opening and closing plate 3 is installed on the rear surface of the cold air passage 2 in the duct cover 1 to move left and right. ) The opening and closing amount of the cold air passage 2 is adjusted according to the movement.

한 냉장실(20) 상측전면에는 조절레버(7)가 설치되는데 상기 조절레버(7)는 일측단은 상기 작동기어(5)의 중심에 고정되고 냉장실 전면측으로 연장된 작동축(6)의 타단에 중심이 고정되어 있다.An adjustment lever 7 is installed at an upper front side of the refrigerating compartment 20, and one end of the adjustment lever 7 is fixed to the center of the operation gear 5 and is provided at the other end of the operation shaft 6 extending to the front side of the refrigerating compartment. The center is fixed.

그리고 상기 작동축(6)은 사절부 하면에서 하향돌출된 고정돌기(8)를 관통하여 회동가능하게 설치된 것이다.The working shaft 6 is rotatably installed through the fixing protrusion 8 protruding downward from the lower part of the trimmer.

이와 같이 구성되는 본 고안 냉장고의 냉장실 냉기조절구조는 사용자가 냉장실(20) 및 냉동실(30) 각각 수납되는 식품의 양 또는 온도에 따라 또는 냉장실 온도에 따라 식품적재시 사절부 하면선단측에 설치된 조절레버(7)를 돌려서 냉장실(20)로 공급되는 냉기량을 조절하게 되게 되는데 예를들면 조절레버(7)를 시계방향으로 돌리면 조절레버(7)와 동일한 작동축(6)에 연결된 작동레버(6)가 시계방향으로 회전하고, 상기 작동레버(6)에 그 상단면의 기어홈이 치합된 개폐판(3)이 냉기통로(2)측으로 이동하여 부분적으로 폐쇄하고 완전히 돌리면 상기 냉기통로(2)를 완전히 폐쇄시킨다.The refrigerator compartment cold air control structure of the present invention refrigerator configured as described above is adjusted to the front end side of the trimming part when the user loads the food according to the amount or temperature of food stored in the refrigerator compartment 20 and the freezer compartment 30, respectively. The amount of cool air supplied to the refrigerating chamber 20 is adjusted by turning the lever 7. For example, when the control lever 7 is turned clockwise, an operating lever connected to the same operation shaft 6 as the control lever 7 is provided. 6) rotates clockwise, the opening and closing plate (3) in which the gear groove of the upper surface is engaged with the operation lever (6) is moved to the cold air passage (2) side partially closed and turned completely, the cold air passage (2) ) Is completely closed.

반면에 조절레버(7)를 상기와 반대로 돌리면 상기 개폐판(3)이 냉기통로(2)를 부분적으로 개방하고 완전히 돌리면 상기 개폐판(3)이 상기 냉기통로(2)를 완전히 개방하게 된다.On the other hand, when the control lever 7 is turned in the opposite direction to the above, the opening and closing plate 3 partially opens the cold air passage 2, and when fully turned, the opening and closing plate 3 opens the cold air passage 2 completely.

따라서, 냉장실(20)로 공급되는 냉기량이 조절되게 되는데 본 고안에서는 조절레버(7)를 사절부하면 선단에 설치하였으므로 조작이 매우 편리하고 또한 냉기통로(2)의 개폐량을 조절하는 개폐판(3)을 송풍팬(50)으로부터 적게 미치는 냉장실 냉기덕트 하단의 덕트커버내에 설치함으로써 미세조절이 가능한 것이다.Therefore, the amount of cold air supplied to the refrigerating chamber 20 is adjusted, but in the present invention, since the adjustment lever 7 is installed at the tip, the opening and closing plate for controlling the amount of opening and closing of the cold air passage 2 is very convenient. 3) can be finely adjusted by installing in the duct cover of the lower part of the refrigerating chamber cold air duct which lessens the blower fan 50.

이상에서 상세히 설명한 바와 같이, 본 고안 냉장고의 냉장실 냉기조절구조는 냉장실 냉기통로의 개폐량을 조절하는 개폐판을 송풍팬으로부터 압력이 적게 미치는 냉장실 냉기덕트 하단의 덕트커버내의 냉기통로의 배면에 설치함으로써, 냉장실 냉기량을 미세하게 조절할 수 있는 효과가 있으며, 조절레버를 사절부 하면선단부에 설치함으로써, 조작이 편리용이한 효과가 있는 것이다.As described in detail above, the refrigerator compartment cold air control structure of the present invention refrigerator is provided with an opening and closing plate for controlling the opening and closing amount of the refrigerator compartment cold air passage on the rear side of the cold passage in the duct cover at the bottom of the refrigerator compartment cold air duct, which has a low pressure from the blower fan. , There is an effect that can be finely adjusted the amount of cold air in the refrigerating chamber, by installing the control lever at the tip of the trimmer, there is a convenient effect of operation.
